Popis: Polycomb group gene silencing Histone proteins wrap around DNA to form nucleosomes that package metazoan DNA into the nucleus. Chromatin compaction is also believed to be critical for the repression of homeotic genes by the Polycomb repressive complex 1 (PRC1) during development. Lau et al. used mutagenesis and expression analyses to examine this gene silencing mechanism. Altering the PRC1 compaction region affected transcriptional repression and patterning of the mouse body axis. Thus, chromatin compaction may drive the stable and heritable silencing of genes involved in body patterning. Science , this issue p. 1081
